Motorcycle Overview

Engineered with all the reliability and durability youve come to expect from Yamaha, the 2-stroke YZ250X was born to win cross-country races.

Features may include:

Engine

GNCC-Tuned YZ250 Power

Based on the legendary YZ250 249cc liquid-cooled reed-valve-inducted two-stroke engine, the YZ250X utilizes a revised compression ratio, exhaust port timing, revised Yamaha Power Valve System (YPVS) timing, and a model-specific CDI unit—all focused on creating a wide, controllable power character ideal for cross-country racing.

Revised Power Valve

The YZ250X features the patented Yamaha Power Valve System—with broader opening timing compared to the YZ250 for smoother power—to combine bottom-end acceleration with strong midrange and eye-opening top-end.

Narrow Exhaust Pipe

Unique compact exhaust expansion chamber is designed especially for the YZ250X, improving both horizontal and vertical clearance on tight, technical trails, while still providing excellent exhaust efficiency.

Chassis/Suspension

YZ250-Based Frame

A carefully engineered aluminum frame and swingarm give the YZ250X the famous handling proven by the championship winning YZ250 motocross machine on tracks around the world.
